S'IPEGIFICATION forming part of Letters Patent No. 704,773, dated July 15, 1902.

' Application filed'April'9,"1902. Sonia-1N0. 102,143. (No model.)

To all whmn it'vncty concern.-

Be it known thaUI,A LB ERT J. BEHRENS, a.

difficult task of forcing l'the threaded end of the hoop through a hole'in the lug or shoe; third, ,topermit the nut to be turned easily and rapidly witha wrench, and, fourth, to

secure the washer to the log. I accomplish these objects by means of the device illus-' trated in the accompanying drawings, in which 7 Figure 1 is a perspective view of the log with the washer in place; Fig. 2, a perspective view of thewashery-Fig. 3, a vertical section throughlA B,.I ig. 1, or along the broken line, Fig. 4. Fig. 5 is a front view of the washer with a slotted opening.

Similarletters refer to similar parts through-' out the drawings.

The body of the lug f, which I designate as the shoe, has an opening 0 d, through which the hoop,'consisting of arod of round iron, is passed. A portion a of this opening is in'the vertical bridge 1' of the shoe, anda portion d is in the bed-plate of the shoe. This is to facilitate stringing the shoe on the hoop-rod. Wingse 6 project from the body of the shoe, which fit in grooves h, cast in the washer to. The purpose of these wings is to hold the washer a in place. Ribs b b b I) serve to strengthen the shoe. The washer Ct is shown in Figs. 2 and 5. The opening o'may be circular or elongated in shape, or it may be a slot extending to the exterior of .the washer, as shown at 0, Fig. 5. Mywasher has grooves h h casttherein, designed to fit over wings e e on the shoe, and it also has a projecting lip is, designed to fit beneath a projection on on the shoe. The grooves h h and the lip It, with their complements on the shoe, are for the purpose of holding the washer in place when.

the hoop-rod is tightened by means of the nut 11. When the nut n is loosened, the washer can be detached from the shoe.

Iupractice my lug is used as follows: The shoe is strung on the hoop-rod byinserting the rod through the opening 0 d. The hoop is then placed around the tank and held in position by nails, as usual. The washer, with either circular or slotted opening, is placed on the threaded end of the hoop-rod and the nut given a few turns. The hoop is then sprung into place, the washer bein'gbrought into the square opening in the shoe, when upon being released the spring of the rod will bring the washer into place with the wings e e of the shoe in the grooves 7th of the washer and the lip 75 of the'washer under the projection m of the shoe, The nut can now be tightened as usual.

There-is more freedom for turning the nut than in lugs heretofore in use so far as I am aware. The washer is made with an angle The angle between the frontand back of the washe'r'is'preferably made greater for small tanks than-for large ones.

- The groovesh h of the washer a and the wings e e of theshoe f may be omitted, retaining the lip 7t on the washer and the projection men the shoe, or the lip k of the washer and the projection m of the shoe may be omitted, retaining the wings e e of the shoe and the grooves h h of the washer when the lugs are designed for small tanks not requiring such great strength to hold the washer in place in the shoe.- I do not dispense with the grooves h h and the lip of the washer and the wings e e and projection m of the shoe in the sa'meilug, for that would destroy one of the principal features of my invention.

'.I am aware that washers with circular and variously-shaped openings, including'slotted openings, are common articles of commerce, and I do not claim such a simple washer with such openings; but

I do claim the following:

l. The combination, in a tank-hoop log, of a movable washer having a lip designed to fit beneath a projection on the body of the shoe and an opening to receive the threaded end of the hoop-rod, with a shoe having an opening to receive the hoop-rod and a projection designed to fit over a lip on the washer, all as described and for the purposes specified.

2. The combination, in a tank-hoop lug, of a movable washer having grooves designed to fit wings on the shoe and. an opening designed to receive the threaded end of the hooprod, with a shoe having wings designed to fit grooves in the washer and having an opening designed to receive the hoop-rod, all as described and for the purposes specified.

3. The combination, in a tank-hoop lug, of

a washer having its two faces at an angle with each other and having grooves designed to fit wings on the shoe and a lip designed to fit beneath a projection on the shoe, with a shoe having wings and a projection designed to fit grooves and a lip respectively on the washer and having an opening designed to receive the hoop-rod, all as described and for the purposes specified.
